IT WORKS! finally!

We can now start deploying OD4B in EDU tenants with IT handling provisioning

here is the steps needed to perform this as of today, hoping it won’t break down on us again.

Firstly connect to Sharepoint online:
Information from https://technet.microsoft.com/en-us/library/fp161372.aspx
(you need to download & install SPO Powershell module @ http://go.microsoft.com/fwlink/p/?LinkId=255251)

Script:
$adminUPN=”<the full email address of a SharePoint Online global administrator account, example: jdoe@contosotoycompany.onmicrosoft.com>”
$orgName=”<name of your Office 365 organization, example: contosotoycompany>”
$userCredential = Get-Credential -UserName $adminUPN -Message “Type the password.”
Connect-SPOService -Url https://$orgName-admin.sharepoint.com -Credential $userCredential

After that follow the steps in this article:

The script is a bit too big to paste straight off as text in this post.
Remember to download the SharePoint Online Client Components SDK.
Also the admin account used to run this script needs to be Global admin & have a license assigned that includes SPO.

Happy OD4B deploying!
